Diffused Aeration Systems for Biological Wastewater Treatment

The Envirex® brand from Evoqua offers a complete line of coarse and fine bubble diffusers

Evoqua application and process engineers can provide complete technical support for system design and proper diffuser selection. A variety of diffuser materials are available to best suit the application.

Recent independent testing of the Diamond™ S Plus membrane disc fine bubble diffuser have shown significant cost of ownership benefits for new or replacement membrane disc systems. 

 Fine bubble diffusers

​​DualAir® fine bubble diffuser systems provide heavy duty piping  and components for long term, trouble free operation. The unique dual pod concept saves installation time by eliminating 30-50% of the required air headers. The DualAir system incorporates the efficient and durable Diamond™ S Plus membrane or ceramic disc diffusers.

  
MonoAir™ single pod diffuser systems are a cost-effective alternative to DualAir systems. MonoAir diffusers are factory solvent welded to the crown of the pipe to ensure a reliable connection and include the Diamond S Plus membrane for high oxygen transfer efficiency.


FlexDisc™ fine bubble membrane diffusers can be used with a variety of piping systems. Diffusers attach to the piping with an NPT threaded connection and incorporate the Diamond S Plus membrane disc diffuser.

 

FlexDome™ Fine Bubble Diffusers offer a patented bolt-on design allowing for the retrofit of the ceramic dome media while keeping the rest of the header piping system intact.  

 

Rex-Flex™ fine bubble membrane diffusers allow for excellent process aeration efficiency.  When air is turned on, the membrane expands and rises off its seat and the apertures open to release a controlled, energy efficient stream of bubbles. Installation is easy and provides superior process flexibility while reducing energy costs.

 Coarse bubble diffusers

Discfuser® coarse bubble diffusers are used in aerobic digesters or sludge holding tanks and offer the advantage of sealing the piping system when the air is turned off.

 

Wideband™ coarse bubble diffusers can be used in a variety of aeration and mixing applications. Diffusers and piping are available in 304L or 316L stainless steel.

 

SnapCap™ coarse bubble diffusers consist of an EPDM diaphragm that seals the piping system when air is turned off and can be used PVC or stainless steel piping.
